/* This file defines some "level 0" kernel functions for SPARC V8 */
/* These are optimised for SuperSparc */
/* The following symbols are defined in this file : */
/* divll bfffo (& tabshi) */
/* But divll have to use hiremainder, so it is different when */
/* hiremainder is inline or not */
/* If libpari.so is compiled with gcc, you should compile all */
